SPECIFICATION forming part of Letters Patent No. 598,122, dated February1, 1898. Application filed November 16, 1892. Serial No. 452,220. (Nomodel.)

To all whom it may concern.-

Be it known that 1, JOHN H. STONEMETZ, a citizen of the UnitedStates,residin g at Brooklyn, in the county of Kings and State of NewYork, have invented a new and useful Improvement in Oiling Devices, ofwhich the following is a specification.

The aim. of this invention is to improve the construction ofprinting-presses; and it especially relates to a means for supplying oilto a second or other impression-cylinder to prevent ofiset on suchcylinder while the sheets or web are printed thereby.

To this end the invention consists of the device described and claimedin this specification and illustrated in the accompanying drawings, inwhich- Figure l is a side elevation of part of a machine, showing theapplication of my improvement; and Fig. 2 is a plan of the same.

Referring to the drawings and in detail, A and B represent twocylinders, which are geared together by means of the gears O and D,fastened on the outer ends of the shafts of the same, as shown.

The cylinder B is supposed to be the second impression-cylinder eitherof a rotary webperfecting press or a double-cylinder printing-machine,and the cylinder A is supposed to be either the second type-cylinder ofa rotary printing-press or the first impressioncylinder of adouble-cylinder printing-press.

Fastened on the shaft of the cylinder 13 is a small gear E, which mesheswith and drives a gear F, fastened on the end of a small shaft which isjournaled in a frame 30, extending up and fastened to the main frame 20,as shown. Fastened to the frame 30 are brackets H andH, in which ismounted a vertical shaft 1, having a keyway I, and mounted on thisvertical shaft I is the adjustable frictiondisk J, which has a keyfitting into the keyway I, and which has a screw J, by which the samemay be secured in any adjusted position. Fastened on the shaft I is aworm K, which meshes with and drives a wormwheel L, fastened on the endof the fountainroller M.

N represents an oil-fountain of the usual construction secured to thebracket H, of

the peripheral speed of the plush roller 0 and the impression-cylinder Bwill be the same.

The plush roller 0 is vibrated axially by means of any of the well-knownmechanisms as, for example, by means of cam Q, secured to the shaft ofthe same, which cam Q has a cam-slot Q, which engages with aroller R,secured to the bracket R, whereby as the plush roll is turned the samewill be moved back and forth axially over the impressioncylinder B toevenly spread the oil thereon, and this axial movement will not effectthe mesh between the gears P and D, as the gear P is made of narrowerface than the gear D, as shown.

The fountain-roll M is geared soas to turn very much slower than theplush roll 0, the plush roll 0 simply running against the same andtaking the oil therefrom, whereby only a slight amount of oil issupplied to the roll 0, and which amount of oil can be regulated andadjusted by regulating the speed of the fountain-roller M, which is doneby adjusting the friction-disk J, so that the shaft I will be driven atthe desired degree of speed. The reduction in speed is obtained by usingthe wornrgear, which, as well known, greatly reduces the speed. Theadvantages of this construction are that all the complicatedductor-rollers and equivalent mechanisms are dispensed with,the samefunction being obtained by the slow speed of the fountain-roll and theslip between the fountain-roll and the plush roll 0.

The plush roll 0 need not necessarily be arranged to bear directly onthe oil-fountain roll M, but, if preferred, 1 may employ any of theordinary systems of intermediate rolls for conveying oil from theoil-fountain to the plush roll.

The impression-cylinder B may be the second impression-cylinder of adouble-cylinder printing-press, in which case the cylinder A would bethe first impression-cylinder, and sheets would be fed from. afeed-board V first to the impression-cylinder A and printed thereby andthen transferred to the impression-cylinder B and printed a second timethereby, or, again, the cylinder B could be the secondimpression-cylinder of a rotary webperfecting press, in which case thecylinder A would represent the second type-cylinder, and the web couldbe led around the impression-cylinder B, as by means of guide-rollers Xand R. Thus it will be seen that my oiling mechanism can be applied toany impressioncylinder in which it is-desired to oil the surface of thesame to prevent offset.

Having thus fully describedmy invention, what I claim, and desire tosecure by Letters Patent, is-- 1. The combination oftheimpression-cylinder, an oil-fountain, an oil-fountain roller, adistributer roller engaging the impressioncylinder and taking oil fromthe fountainroller, and gearing for turning the oil-fountain roller at aslower peripheral speed than the distributer-roller, whereby there willbe a peripheral slip between the distributer-roller and thefountain-roller, so that the distributer-roller can deposit a uniformthin film of oil upon the surface of the impression-cylinder,substantially as described.

2. The combination of an impression-cylinder, an oil-fountain, anoil-fountain roller, a distributer-roller, said distributer-roller betheoil-fountain roller and the impressionl cylinder, and means for drivingthe oil-fountain roller at different relative speeds to regulate theamount of oil transferred to the distributer-roller, substantially asdescribed.

3. The combination with the impressioncylinder of the oil-fountain andfountain-roll, means for taking the oil from the fountainroller anddepositing the same upon the impression-cylinder, gearing for rotatingthe fountainroller,'and a continually-rotating disk, and an adjustablefriction-disk, cooperating therewith for imparting an adjustable speedto the gearing for driving the oil-fountain'roller, substantially asdescribed.

, 4. The combination with the impressioncylinder of the distributerroller bearing thereon, the oil-fountain and oil-fountain roller, thedistributer-roller, also, bearing on the oil-fountain roller, theworm-wheel mounted to turn with the oil-fountain roller, the
